WRENCH.

Y SPECIFICATION forming* part of Letters Patent N0. 761,645, dated June '7, 1904.

Application filed October 2 1903.

To all whom it may concern.-

Beit known that I, ANDREW BAUGHMAN, a citizen of the United States,residing at Lowellville, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Wrenches, of which the following'is a full, clear, and exact description, referencebein g had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in wrenches; and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claim. I I

In the drawings, Figure 1 is a side elevation of the wrench,show ing the sliding jaw gripped to the shank of the tool. Fig. 2 is a combined longitudinal section. and elevation of the same. Fig. 3 is a side elevation showing the sliding jaw released and in position to be moved in either direction along the shank, and Fig. 4is a transverse section on line 4 4 of Fig. 1.

The object of my invention is to construct a nut-wrench whose sliding jaw can be manipulated and slid into position against a nut without the use of screw adjusting devices.

In detail the invention may be described as follows: Referring to the drawings, 1 represents the handle of the wrench, 2 the toothed shank thereof, and 3 the terminal fixed jaw. The sliding jaw 4 has pivotally securedtheret0 one end of a link or arm 5, provided with a toothed section adapted to engage the teeth of the shank, the opposite end of the arm terminating in a pawl 6, also adapted to engage the shank for purposes of taking up the strains at that end of the arm. Located adjacent to the pawl 6 is ahead or saddle 7, straddling the shank, one of the embracing side walls of the saddle being extended a suitable distance below the lower edge of the shank and havingv formed therein an open recess 8 for the reception of a locking-arm 9, whose one end is piv-A oted to the lower edge ofthe opposite em- Serial N0- 175,524. (No model.)

bracing wall of thesaddle. When the saddle is resting upon the shank, the arm 9 is swung across the lower face of the shank and into the recess 8, Figs. 1, 2, 4, when the parts are securely locked against 'longitudinal movement. To adjust the sliding jaw to some other position,the arm 9 is swung open either ninety degrees, Fig. 3, or one hundred and eighty degrees, dotted position, Fig. 4, permitting the saddle to be lifted out of engagement with the shank, Fig. 3, and permitting the sliding jaw to be shoved along the shank to any desired position.' When once adjusted, the parts may be again locked, as shown in Figs. 1, 2,l

and 4. Y g

I do not, of course, wish to belimited to the details here shown, as they may in a measure be altered without departing from the spirit or nature'of the invention.

Having described my invention, what I claim is- In a wrench, a suitable toothed shank, a fixed jaw and a sliding4 jaw for the same, an arm or link having one end pivotally secured to the sliding jaw, and having a toothed section adapted to engage the teeth ofy the shank, a terminal tooth or pawl for engaging the teeth of the shank, a saddle located adjacent to the pawl and straddling the shank, the latter having one of its side walls extended a suitable distance beyond the lower edge of the shank, said extension having an open recess formed therein and alocking-arm having one end pivoted to the lower edge of the opposite side wall of the saddle and adapted to be swung into said recess, and lock the parts against longitudinal movement, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses. 4

ANDREW BAUGHMAN.
